DESCRIPTION
Enable/shutdown input. When EN is asserted high (V
is asserted low (V
Positive input voltage for the regulator. If this input pin is greater than 2 inches from the main input
filter, a 10µF ceramic capacitor is recommended for adequate filtering.
The regulated voltage output. An output capacitor of 10µF is recommended to minimize any tran-
sient load disturbances under normal operating conditions. Additional output capacitance can be
used to further improve transient load response.
Feedback input. When ADJ is grounded, the device enters fixed voltage mode. When ADJ is con-
nected to an external resistor network, the device operates as an adjustable regulator. The Adjust
pin can also be tied directly to the OUT pin which configures the CM3004 as a 1.2V regulator.
The negative reference for all voltages. Also functions as a thermal path for heat dissipation.
